Regulations

FIA currently defines several categories of GT cars with the top two specifications being GT1, or Grand Touring Cars, and GT2, or Series Grand Touring Cars. Each category has an annual driver champion, team champion, and manufacturer champion. Both categories are based on production road car designs, which must be produced in a minimum quantity of 25 examples to qualify. Both types may undergo significant modifications from the road car they are based on, but GT1 allows the use of exotic materials, better aerodynamics, larger brakes, wider tires and larger engine admission restrictors.
